Flask import problem with Python 3 and __main__.py

Flask suggests the following file layout:
runflaskapp.py
flaskapp/
__init__.py
runflaskapp.py contains:
from flaskapp import app
app.run(debug=True)
flaskapp/__init__.py contains:
from flask import Flask
app = Flask(__name__)
Running this with 'python3 runflaskapp.py' works fine. However it
seems to me that a more Python3onic way of doing this would be to
rename 'runflaskapp.py' as 'flaskapp/__main__.py' and then run
the whole thing as 'python3 -m flaskapp'. Unfortunately this doesn't
work:
$ python3 -m flaskapp
* Running on http://127.0.0.1:5000/
* Restarting with reloader
Traceback (most recent call last):
File "/home/username/src/flaskapp/__main__.py", line 1, in <module>
from flaskapp import app
ImportError: No module named 'flaskapp'
Does anyone know why and how to fix it?
